UNTTED STATES CHRISTOPHER C. FLEMING, OF DALLAS, TEXAS.

SAW-TOOTH.

Specification of Letters Patent.

Patented Feb. 20, 1906.

Application filed January 5.1904. Serial No. 187,771-

T0 aZZ whom it may concern.-

Be it known that I, CHRISTOPHER C. FLEM- ING, a citizen of the United States, and a resident of the city of Dallas, county of Dallas, and State of Texas, have invented an Improved Construction in Saw-Teeth, of which the following is a specification.

My construction of teeth are-set on the saw-blade in unbroken series from end to end of the saw-blade, being uniform in length, size, bevel, and pitch, set so as to dig or pierce when in operation.

The purpose of my device is to obtain a construction in saw-teeth which will cut the timber without any downward weight of the operator and that will out very fast and be easy to manipulate.

This construction of saw-teeth is to be used on bucksaws, handsaws, one-man crosscut-saws, and all other kinds of saws to be used by one man.

Referring to the drawings, Figure 1 represents' a portion of a saw, showing my 1mproved knife-tooth. Fig. 2 1s a sectional end view of same. Flg. 3 1s a side view of a pair of teeth, right and left. Fig. 4 is a sectional v end view of same.

A represents the points of the teeth.

B represents the bottom of the front of the pitch.

0 represents the bottom of the rear of the teeth.

Pitch of the teeth would be the distanc from a to a. The base of the teeth would be from b to c. In my teeth I make the depth equal to the base, or one and one-half times greater than the base, or equal to the pitch, or one and one-half times greater than the pitch. The angle or bevel of my cutting edge is forty-five to sixty degrees. The teeth are made alternately right and left, tooth and tooth, and looking lengthwise down the sawblade shows a double line of needle-points or great angular points.

Having thus described my construction of saw-teeth in such concise and plain language as I think will enable any one versed in the art to construct and use the same, what I claim is In a saw, teeth uniform and in unbroken series, being in length equal to the length of the base, or equal to one and one-half times the length of the base, beveled forty-five to sixty degrees, the front cutting edge of the teeth 'being approximately straight, or at about right angle with the saw-blade, substantially as described and shown.
